Cross TabBar navigation broken on iOS

[albyrock87]

Description

On iOS, using TabBar and navigating to a new Tab also pushing a page onto the navigation stack does not work:

• No exception is thrown
• Task is not completed

var shell = Shell.Current;
try
{
    // "main" is the `TabBar`
    // "Foo" is a different `ShellContent`
    // "Bar" is a page registered in the `Routing`
    await shell.GoToAsync("//main/Foo/Bar");
}
catch (Exception ex)
{ 
    // Add breakpoint here => not hit
    Console.WriteLine(ex.Message);
}
finally
{
    // Add breakpoint here => not hit
    Console.WriteLine("Finally");
}

This is probably a duplicate of #16568 but the public repository I've attached to reproduce the issue is less complicate to look at.

Hi @albyrock87, thanks for your repository! I've made some investigation and this issue is related, but not the same as #16568

The later one is about the navigation inside the 'more' tab and yours is about the navigating between the visible-tabs-in-toolbar. I have a fix for your issue: #22655

@kubaflo I also have a fix for my issue: #22574
anyway, I guess two is better than one 😉
And actually yours looks better (hoping it doesn't cause issues on other platforms).
Thanks for looking into it, I appreciate!
